Photographer Sven Torfinn recently visited Galcayo, a divided town in Somalia where MSF is working to deliver desperately-needed health care amid drought and malnutrition exacerbated by years of conflict.

Doctors Without Borders/Médecins Sans Frontières (MSF) teams are providing medical and psychological care to survivors of the earthquake and tsunami disaster that struck northeastern Japan on March 11, 2011. The national response to the disaster has been massive, so MSF is focussed on meeting the needs of small pockets of the population in remote areas.

MSF has been treating women with cholera who are in labor and in the late stages of pregnancy in Port-au-Prince, Haiti, since November. Many of the women have lost their babies due to the effects of cholera.

While documenting the aftermath of the earthquake in Haiti, photographer Nicola Vigilanti met a brave young girl named Mirlanda who was receiving physiotherapy and post-operative care for her quake-related injuries at MSF's Saint Louis Hospital. Mirlanda's inspiring struggle for recovery is just one story from the many thousands of Haitians in the rehabilitation process.

In Sukkur, Sindh Province, as well as other areas in Pakistan, people displaced by the flooding that began at the end of July are still suffering. About 1,198 Pakistani MSF staff, with 135 international staff, have so far conducted more than 49,500 medical consultations and are distributing 1,250,400 liters (330,320 gallons) of clean water per day in Sindh, Punjab, Balochistan, and Khyber Pakhtunkhwa provinces.

Two weeks after floods hit areas of Pakistan, MSF has sent 110 tons of water-and-sanitation equipment, drugs, and medical and logistical material into the country. More supplies will follow according to the needs identified. More than 100 international staff are currently working alongside 1,200 Pakistanis in MSF programs in Pakistan.

This slideshow is narrated by an MSF communications officer, who also took the photographs during a two-week visit to Haiti in March, 2010. He accompanied MSF field staff on assessments of living conditions in makeshift camps where people had been living without basic assistance.
